The purpose of this paper is to show the application of Corporate Social Responsibility in selected Public companies in the Republic of Croatia with examples of good practices in order to point out the importance of public companies' influence on all stakeholders and to accelerate and expand the long-term sustainable development. Companies were selected based on previous research. Previous research, Research of the level of understanding and implementation of Corporate Social Responsibility in state owned companies in Croatia (Plećaš and Matešić, 2016) showed that 53% of respondents in a sample of public companies in the Republic of Croatia declare that they practice Corporate Social Responsibility (CSR). The goal of this paper is to further explore those CSR activities, what is it that they practice under CSR and how these activities are being communicated. The hypothesis of the work is that most of the selected companies, although positively declared about the existence of CSR activities, are not capable of conducting and publicly communicating such processes. The process of implementing such activities is very important from the aspect of division of tasks and responsibilities. For the quality of CSR programs, it is important to have support from the company’s management or the responsible person and from which direction the initiative came. Research will explore what are the most common areas covered by CSR and which stakeholders are most often targeted. Research will explore when they started with CSR activities, how they implemented it, and whether information on the activities are publicly available. Research will use desk study on a selected sample of eight public companies, which in the sample of 15 respondents in the previous research positively responded on the question of the existence of CSR practices. Due to a relatively small sample, the research will use qualitative methodology, case study methodology in terms of interviews. Therefore, the results of the research are not statistically significant, but qualitatively show the degree of application and understanding of CSR activities in public companies in the Republic of Croatia and their communication to stakeholders.
